How to Keep Unpasteurized Juice Fresh

by Maya Black

Much of the juice sold in supermarkets is pasteurized, meaning it has been heat-treated to kill bacteria that cause food-borne illnesses. Some supermarket delis, cafes and restaurants, however, sell fresh-squeezed juice. Squeezing and blending juice on-site allows juice sellers to create tantalizing flavor combinations, but not everyone can consume freshly squeezed beverages, especially children, pregnant women, the elderly and anyone with a compromised immune system. Whether you buy unpasteurized juice or make it yourself, it must be stored properly to be consumed safely.

Place a thermometer in your refrigerator to check the temperature. The refrigerator's temperature must be 40 degrees Fahrenheit or colder to keep harmful bacteria at bay.

Wash a glass or plastic container to ensure that it's bacteria-free. Transfer the fresh-squeezed juice from your juicer, blender or to-go cup into the container, close it tight and place it in the fridge. Store unpasteurized juice for no longer than three days.

Fill a large bowl with ice and set your juice pitcher down in it if you plan to serve fresh-squeezed, unpasteurized juice at a family breakfast or luncheon. Let everyone know that the juice is unpasteurized, so that anyone who shouldn't consume it can avoid it.

Items you will need
  • Unpasteurized juice
  • Thermometer
  • Container with lid


  • If you juice regularly and wish to keep some for more than a few days, place it in plastic containers or resealable bags and store it in the freezer.
  • Follow the sell-by dates printed on store-bought unpasteurized juices and toss any juice past its expiration date.
